For those that want the best audio products in the world, VAC is the #1 producer of tube preamps and amps in the industry. 

VAC started with a passion about breathing realism and life into reproduced music, to making it sound as much like the real thing as possible. VAC products are masterpieces because they allow each recorded performance to be the masterpiece the musicians intended.

​

The difference between a good amplifier and a great amplifier resides in the details, and in the passion of the designer. One of the reasons for superiority of VAC equipment is that VAC uses vacuum tube technology almost exclusively. After almost 100 years since its invention, the triode vacuum tube remains the most linear (accurate) amplifying element known producing superior sonic performance. A tube amplifier, properly designed, preserves far more of the vitality of the original performance. Tubes simply bring the music back alive. This is why the world’s foremost guitarists use tube amplifiers, and why vacuum tube microphones and processors are highly prized by the world’s best recording studios. Tubes do have a sound that is different from solid state amplifiers, and one that happens to make amplified music sound better to the human ears and brain.
